PS tutorial for cutting out photos from ID photos - What is the method to quickly cut out photos from PS ID photos?

How to use PS to cut out pictures?

PS cutout method

1. Magic wand method - the most intuitive method

Applicable scope: The color difference between the image and the background is obvious, and the background color is single. Image borders are clear.

Method intent: Get the image by removing the background color.

Method Disadvantage: Not useful for loose hair.

How to use: 1. Click the "Magic Wand" tool;

2. In the "Magic Wand" toolbar, check the "Continuous" item;

3. Fill in "20" for the "Tolerance" value. (The value can be adjusted after seeing the effect);

4. Use the magic wand to click on the background color, and a virtual frame will appear surrounding the background color;

5. If the virtual If you are not satisfied with the range of the box, you can press CTRL+D to cancel the virtual box first, and then adjust the "Tolerance" value in the previous step;

6. If you are satisfied with the range of the virtual box, press DELE on the keyboard key, delete the background color, and you get a single image.

2. Color range method - fast

Applicable scope: The color difference between the image and the background color is obvious, the background color is single, and there is no background color in the image.

Method intention: Cut out the image through the background color.

Method defects: Not applicable to images with background color.

How to use: 1. Use the color straw to pick up the background color;

2. Click the "Color Range" function in the "Select" function in the menu;

3 , put a check mark in front of the "Invert" item, and the image will be selected after confirmation.

3. Magnetic noose method - convenient, accurate, fast and my commonly used method

Scope of application: clear image boundaries.

Method Intent: The magnetic noose will automatically recognize the image boundary and automatically adhere to the image boundary.

Method defects: Boundary points need to be placed carefully where the boundaries are blurry.

How to use: 1. Right-click the "Magnetic Loop" tool and select the "Magnetic Loop" tool;

2. Use the "Magnetic Loop" tool to place it along the edge of the image Boundary point, a line will be automatically generated between two points and adhered to the image boundary.

3. Boundary points need to be placed carefully where the boundaries are blurry.

4. After the noose is closed, the cutout is completed.

4. (Lose) feathering method - rough processing

Scope of application: rough cutout.

Method intention: rough cutout, not accurate.

Method defect: The image boundary is imprecise.

How to use: 1. Click the "Lose" tool;

2. Use the lasso to roughly surround the image, and the border should be about the same distance from the edge of the image; this Points can ensure the consistency of the subsequent feathering range and improve the accuracy of cutout;

3. Right-click the mouse and select the "Feathering" function;

4. Adjust the feathering value, generally Fill in "20" and after confirmation, the image will be roughly selected. The size of the feather value should be adjusted according to the distance between the border and the image in the previous step.

5. (Lose) pen tool method - the most accurate and labor-intensive method

Applicable scope: image boundaries are complex and discontinuous, and the processing accuracy is high.

Method intention: Completely manually place the boundary points one by one to cut out the image.

Method defect: slow. It takes about 15 minutes to dig out a picture even with your hands and toes.

How to use:

The steps of the pen tool method are as follows:

1. Establish a rough path with the rope casing

(1) Use the "rope tool" Use the "Set" tool to roughly circle the outline of the graphic;

(2) Right-click and select "Create Work Path", and generally fill in "2" for the tolerance.

2. Fine-tune the path with the Pen tool

(1) Select the "Pen" tool and select the second "Path" icon in the Pen toolbar;

(2) Hold down the CTRL key, click on each node (control point) with the mouse, and drag to change the position;

(3) Each node has two radian adjustment points. Adjust the arc between the two nodes to make the line as close to the edge of the graphic as possible. This is a key step for smoothness;

(4) Add nodes: If there are not enough nodes, you can release the CTRL button and use the mouse to move the path increase.

Delete nodes: If there are too many nodes, you can release the CTRL button and move the mouse to the node. When a "—" sign appears next to the mouse, click the node to delete it.

3. Right-click "Create Selection", generally fill in "0" for feathering,,

Press CTRL+C to copy the selection;

Create a new layer or file;

In the new layer, press CTRL+V to paste the selection, and it’s OK!

Shortcut key to cancel the selection: CTRL+D

Note: This tool is not useful for loose hair.

6. Mask cutout method - intuitive and fast

How to use: 1. Open the photo and background image

2. Click the move tool to move the photo Drag the background image

3. Add a mask

4. Set the foreground color to black and select brush 45

5. This way you can rub on the background , rub until satisfied. If you accidentally wipe the wrong place, just change the foreground color to white and you can wipe it back.

A collection of PS cutout methods for beginners, professional version

1. Eraser cutout

Methods, characteristics and scope of application: Eraser cutout means using an eraser to cut out pictures. The eraser tool erases the unused parts and leaves the useful parts. This method is a shape cutout method. It is simple and easy to use, but the processing effect is not good. It can be used for graphic cutout with simple outline lines. But it is mainly used for further processing the effects of cropping with other methods.

Operation steps:

1. Open the picture;

2. Double-click the layer and change the background layer to a normal layer

3. Select the eraser tool, select a larger main diameter of the brush, and roughly erase most of the unused parts

4. Then select a smaller main diameter of the brush, enlarge the image, and perform detailed processing< /p>

2. Magic wand cutout

Methods, characteristics and scope of application: Magic wand cutout is to use the magic wand tool to click on unused parts, or click on the parts you want to use and then invert the selection. , and then delete it, leaving the useful parts. This method belongs to the category of color cutout and is easy to use, but it is not suitable to achieve the expected effect. Therefore, it can only be used for cutout when the color difference between the parts to be used and the parts not to be used is large, or as an auxiliary method for other cutout methods.

Operation steps:

1. Open the picture;

2. Double-click the layer and change the background layer to a normal layer;

9. If it is not ideal, repeat steps 7 and 8 to achieve satisfactory results.

5. Channel matting

Method, characteristics and scope of application: Channel matting is a color matting method, which makes use of the contrast of the color of the object in the three channels of red, yellow and blue. flat characteristics, thereby processing objects in high-contrast channels. First select the channel with high contrast, then duplicate the channel, further increase the contrast, and then use the Magic Wand tool to select the object. It is suitable for cutting out images with little color difference and complex shapes, such as hair, branches, fireworks, etc.

Operation steps:

1. Open the picture;

2. Double-click the layer and change the background layer to a normal layer;

3. Open the channel panel and click on the three monochrome panels of red, yellow and blue respectively to find the channel with the clearest object. In this picture, we click on the blue channel;

4. Change the blue channel Drag the channel to the Create New Channel button below the channel panel and copy the blue copy channel;

5. Image/Adjustment/Levels, adjust the "Input Levels" to enhance the contrast of the object;

6. Image/Adjust/Invert;

7. Use the lasso tool to circle fireworks and other patterns;

11. Select/invert selection, edit/clear; select/deselect

Of course it is a more professional technique There are many more, such as extracting the foreground color and setting it to white, then using an eraser to insert excess color, using enhanced contrast, sensitivity, etc. to extract hair, hair, etc. There are many, many more. However, these methods are difficult to describe, so I will omit some space.

PS Tutorial on PS Cutout Skills

In many tourist attractions, landscape photos can be quickly synthesized to commemorate, that is, portraits are superimposed on fixed landscape pictures, but the production The photos that come out are rather rigid. The Photoshop darkroom makes it easy for us to create a variety of composite photos, and thanks to the powerful functions of Photoshop, it can be completely fake and real, allowing you to "travel around the world" without leaving home.

The prerequisite for success in making this type of composite photo is perfect cutout. The composite object must be perfectly separated from the original background, and then the powerful filter function of Photoshop can be used to create light and shadow effects. . Use PS to change the background of the ID photo, how to pull out the hair

1. First, use the extraction filter tool to cut out the picture.

2. After opening PS, double-click the blank space of the PS panel with the left button and select the picture you want to modify the background. Use the shortcut key Ctrl+J to create a background layer.

3. Click the foreground color in the lower left corner (the default is white) and select a background color you want to change to, such as blue. After confirming, you will find that the foreground color changes from white to blue. Press the shortcut key Alt+Delete, and the background color will change to the blue you just selected.

4. Left-click Filter-Extract in the menu bar, and you will enter the Extract page. Pay attention to the order of steps at this time. First, check the box for forcing the foreground on the right side of the page, click the eyedropper tool on the left side, and then click on the beauty’s hair. At this time, the color under the forced foreground will change to the color of the hair.

5. Click the edge highlighter tool in the upper left corner and apply it on the beauty’s hair and body until the character turns green. The effect is as shown in the picture below. Click OK in the upper right corner. Return to the PS interface. You will find that the original photos have turned into the selected blue color.

6. Select the history brush tool in the left toolbar and use the brush to paint on the character's hair and clothes. Be careful not to apply it on the background. You can enlarge the picture and be careful to apply the edges. If you make a mistake, you can click Edit in the menu bar and take a step back.

7. After the characters and hair are painted, the hair strands are pulled out. You can use the deepening tool to perfect the edges of the hair. Final rendering. What are the ways to quickly cut out PS ID photos?

Detailed explanation of the four cutout methods

1. Tool method - skillfully use the magic wand tool to replace the background

Knowledge Tip: The magic wand tool mainly allows users to select an area with a consistent color (for example, a red flower) or a picture with a dull background without having to trace its outline. The color range selected by the Magic Wand tool can be controlled by the "Tolerance Range" parameter value in the tool options bar. Note that the Magic Wand cannot be used on images in bitmap mode.

The following will be explained with an example. Open a photo in Photoshop, as shown in Figure 1. Let’s analyze this photo first. Its background is relatively dim and the color of the background is relatively similar. In this case, you can use the method of removing the background to realize the cutout of the characters. Figure 1

The creative idea of ????this example is to use the magic wand tool to select most of the background area, and then use the method of adding or deleting the selection to further select it. If there are details that cannot be selected, use the Lasso Tool or the Magnetic Lasso Tool to complete it.

1. After opening the photo in the Chinese version of Photoshop CS, click the Magic Wand tool in the toolbox, and then set the tolerance parameter value to 50 in the tool options bar that appears. Then click the left mouse button on the background of the character, and then you can get most of the background selection. For discontinuous selections, you can select the Magic Wand tool and then click the "Add to Selection" icon in its tool options bar or hold down the Shift key on the keyboard and click on other places you want to select. As shown in Figure 2.

Figure 2

2. Next, further select the background. First click the zoom tool in the toolbox to enlarge part of the photo. Or with the "Add to Selection" icon in the Magic Wand tool option bar selected and appropriately change its tolerance parameter value, then use the Magic Wand tool to click on the unselected background area, which will further increase the Background area selection.

Tips: If you use the Magic Wand Tool to select part of the character, you can use the Magnetic Lasso Tool, and then click "From Selection" in the tool options bar that appears. Subtract” icon and then select the selection. For the small areas in the background that have not been selected, you can use the Lasso tool and select the "Add to Selection" icon for further selection.

3. The next step is to extract the characters. Click the "Select→Invert Selection" command in the menu bar, or press the shortcut key "Ctrl+Shift+I" to invert the selection, and you can select the character. Then press the "Ctrl+C" keys to copy the character, and press the "Ctrl+V" key to paste the character into a new layer 1, as shown in Figure 3. Figure 3

4. Detail modification. Select layer 1 where the character is stored, use the zoom tool to enlarge the character, and use the eraser tool in the toolbox to erase the jagged edges. Then, press the Ctrl key and click the character layer with the left mouse button to select the extracted character, and then click the "Select → Feather" command in the menu bar, or press the shortcut key "Alt+Ctrl+D" to open the Feather dialog box. Enter the feathering parameter value 2 and click the "OK" button. This way the edges of the entire character will appear soft and not too harsh.

Tips: When performing feathering, adjust the feathering parameter value mainly to see the roughness of the edges of the selected character or object. If the edges of characters or objects are rough, you can increase the feathering parameter value appropriately.

5. Adding background. Click the "File → Open" command in the menu bar, find a beautiful background picture in the search range, add the character extracted earlier to the background file, and adjust the position and size.

Then click the "Image→Adjustment→Brightness/Contrast" command in the menu bar to open the Brightness/Contrast dialog box and adjust the brightness of the character to suit the background light and dark. The final effect is shown in Figure 7. Figure 4

Summary of knowledge points: When cutting out images, it is often difficult to distinguish between selected areas and unselected areas. In this case, we can save the selected selection to a new layer, and then reselect it to gradually delete the unnecessary parts. For details that are difficult to deal with, you can use the eraser tool to trim them.

2. Path method - use the pen tool to pick out characters

Knowledge point tip: Path is a method provided by Photoshop for drawing selection boundaries and strokes. It is our right assistant in drawing images. Paths are lines and graphics composed of Bezier curves, which are generally divided into two types: open paths and closed paths. If you want to convert a path into a selection, it must be a closed path. Using paths to extract people is more suitable for photos where the edges and contours of the people are clearer.

Before operating, let’s first observe the photo and think about what tools and methods are more suitable for operating the photo. In this photo, you can see that the edge contours of the characters are relatively clear, so we can use the path tool to cut out the characters from the original background image and place them in the new background.

Let’s get started.

1. Enter Photoshop and open the photo. Click the Pen tool in the toolbox and select the "Path" icon in the tool options bar that appears. The path selected using the pen tool is the path. Next, use the zoom tool in the toolbox to enlarge the image, and then carefully select the outline of the character. The method of checking is as follows:

Start drawing path nodes from any edge of the character. When two or more nodes have been defined in the image, the direction of the path is determined. Continue in this direction to outline other nodes around the character. If a node needs to be repositioned, you can hold down the Ctrl key and click the node to modify it. The nodes are used to move the position of the curve, and the handles that appear on the nodes are used to adjust the curvature of the curve. By adjusting the curvature of the curve, the path can be closer to the edge of the character's outline, as shown in Figure 5. Figure 5

2. After checking the outline of the character, start extracting the character. Press the shortcut key "Ctrl+Enter" to convert the selected path into a selection. You can also click the "Work Path" in the "Path" panel while pressing the Ctrl key to convert it into a selection. Press the "Ctrl+C" key combination to copy the character in the selection, and then press the "Ctrl+V" key combination to paste. At this time, the character will be automatically saved to a new layer 1, as shown in Figure 6. Figure 6

3. Detail trimming. The operation method is similar to the post-operation method of using the magic wand tool to replace the background. First, use the feathering command to feather the outline of the character, so that the edges of the character's outline will not appear stiff and unrealistic. You can use an eraser to trim local areas.

Tips: When using the eraser tool to retouch characters, especially when retouching details on the character’s face, be sure to adjust the size of the eraser tool. The more detailed the part, the smaller the eraser. The wiping tool should be smaller.

4. Finally, add the background and modify the final effect. Click the "File → Open" command in the menu bar, find a background image in the search range, then press the shortcut key "Ctrl+A" to select all the background images, and then press the shortcut key "Ctrl+C" to copy it. Go back to the original file and press the shortcut key "Ctrl+V" to paste the background image. At this time, the system will automatically generate a new layer 2. Then adjust the position of layer 2 with the background image below layer 1 with the characters, and then adjust the size and positional relationship between the characters and the background.

For places where the transition between the character and the background is unnatural, you can click the "Blur" tool in the toolbox and smear on the edges of the character, so that the transition between the character and the background becomes natural. Finally, click the "Filter→Rendering→Lens Flare" command in the menu bar to open the Lens Flare dialog box, set the brightness parameters and lens type, and then add a few more lens flares to the background image to achieve the final effect. The production is completed, as shown in Figure 7.

Figure 7

3. Masking method_Meisha Jieji Laixi

After discussing the two methods of character cutout above, is it possible to extract character images? Already familiar with the method of changing the background? However, there are some same characteristics in the first two methods, that is, when the background color is single or the character outline edges are clear, the success rate of keying is relatively high. However, photos taken in real life often have complex background colors and unclear character outlines, such as hair, which are not easy to process using the above two methods. This problem can be solved more easily by using the fast mask editing mode provided by Hotshop.

Knowledge tip: The mask is actually the so-called mask. It overlays the image and isolates and protects the non-editing areas of the layer from operations on other areas. Use masks to create a selection of any shape and control the appearance of the edges of the selection. Use Quick Mask mode to quickly create and modify very precise selections. After creating a quick mask for the selected area, use drawing tools or filters to modify the selection to expand or reduce the selection to the desired range. Finally, when you exit the quick mask mode and return to the normal mode, The area not covered by the mask becomes a selection and is selected, creating the precise selection you want. After creating a quick mask in an image, you can use almost all the tools and filters to modify the mask.

First, let’s analyze a photo, as shown in Figure 8.

Figure 8

The background color of this photo is relatively complex and has a strong sense of layering. Obviously it is not easy to use the magic wand tool to select a large background area at once, and the outline of the character The connection between the edge and the background is more complicated, especially for hair. If you use the pen tool to draw a path, it will be more troublesome. At this time, you can consider using the quick mask editing method. _Vinegar Sprite: After entering the mask, use the brush to smear the edge outline of the character first, then smear the entire character, then convert it into a selection, and finally extract the character.

1. First set the parameters of the quick mask. After opening the photo in Photoshop, double-click the "Edit in Quick Mask Mode" button below the toolbox to open the Quick Mask Options dialog box, as shown in Figure 13. In this dialog box, you can choose whether to display the color in the mask area or the selected area, as well as what color and how much transparency to use for color display. Usually the default color is red. If the color of the character is reddish, you can choose another color that has a high contrast with red, such as blue, so that it is easy to distinguish. (See Figure 9) Figure 9

2. After entering the quick mask, click the brush tool in the toolbox to start painting. Start painting from the edges of the character's outline first. Set the brush mode to "Normal", the opacity to 100%, and the flow to 100% in the brush options toolbar. What should be noted here is that you must be careful when applying hair, and set the size of the brush smaller and the hardness smaller, so as to facilitate better operation.

Next, start painting along the edge of the character's outline. After painting the edge of the character's outline, you can adjust the brush size to a larger size and paint until the character is completely covered, as shown in Figure 10. Show.

Tips: To delete the painted area, you can choose the foreground color to be white, and then erase it with a brush. Use the zoom tool in the toolbox when painting, which will make the operation more convenient.

3. After the painting is completed, click the "Edit in Standard Mode" button under the toolbox to return to the standard editing mode. At this time, we can see that the area outside the character outline has become a selection. , as shown in Figure 11. Because what we want is a character, we execute the "Select→Inverse Selection" command in the menu bar to select the character.

Figure 11

4. To extract the characters into a new layer, follow the steps and methods shown in the two examples in the previous issue. Press the shortcut key "Ctrl+C "Copy the character, and then press the shortcut key "Ctrl+V" to paste the character into a new layer 1. After hiding the "Background" layer, you can see the individual character, as shown in Figure 12. From Figure 5, you can see that the details of the character, especially the more complex hair, are also handled very well.

_12

5. Finally, we choose a good-looking background image, place the characters in it, and modify the brightness, size, and position of the characters, especially the blur tool for edge details such as hair. for processing. Click the "Filter→Blur→Gaussian Blur" command in the menu bar to open the Gaussian Blur filter dialog box and set the blur parameters. This will make the character look more natural and the final effect will be achieved, as shown in Figure 13. Show. Figure 13

Four. Filter method_δRui Kan韮 Mou Jujusi

Once you have mastered the first three methods, you can basically cut out the characters in the photo easily. It comes out, especially using the fast mask editing method to handle the details better. However, in some cases, the effect of using masking technology to process the edges of hair and skin is still not ideal. In this case, you can consider using the filter method, and use the extraction filter to accurately cut out the characters.

Knowledge tip: Compared with the first three tools, the extraction filter provides more professional and powerful tools and parameters. The Extraction filter provides an advanced method for isolating a foreground object and clearing its background on a layer. Even objects with subtle, complex, or indeterminate edges can be clipped from the background without much effort, and the tools in the Extract dialog box allow you to specify the portion of the image to be extracted. The main steps are to first mark the edges of the object and fill in the parts to be retained. You can preview it, and then modify the extracted effect.

Let’s take a look at a photo first, as shown in Figure 15.

Figure 15

As you can see from this photo, the background color looks similar to the color of the character’s clothes, and the hair is messier. If you want to accurately To pull it out from the background, use the Extraction filter.

1. Open the photo in Photoshop, then click the "Window → Layer" command in the menu bar or press the shortcut key F7 to open the layers panel. Right-click on the background layer, select the "Copy Layer" command in the pop-up shortcut menu, and create a "Background_North End Grid Ji Ke H Slow 笤 Chen Fan! Ammonia Dust_Copy" layer as the currently edited one After adding the layer, click the "Filter→Extract Filter" command in the menu bar to open the Extract Filter dialog box.

On the left side of the dialog box are some tool buttons for extracting filters, from From top to bottom are the Edge Highlighter Tool, Fill Tool, Eraser Tool, Eyedropper Tool, Clear Tool, Edge Modification Tool, Scale Tool, and Grabber Tool. On the right side of the dialog box is the parameter setting of the extraction filter. Due to space reasons, there is no further explanation here.

2. After understanding the meaning of each component of the extracted filter, start operating on the characters. Click the Zoom tool to enlarge the character image, then click the Edge Highlighter tool, and adjust the "Brush Size" parameter value on the right to be smaller, which will help paint the character's hair. You can use the eraser tool to erase the wrong parts. First, paint the edge outline of the character. After the drawing operation is completed, click the fill tool on the left toolbar to fill in the character's skin. At this time, click the "Preview" button on the right side of the dialog box, and you can quickly see the extracted renderings in the preview window.

3. After the above operations are set, click the "OK" button in the dialog box to exit the "Extract" filter. At this time, you can hide the "Background" layer by clicking the "eye" sign on the left side of the "Background" layer in the layers panel, so that you can see the "Background" layer we just used "Extract" filter to operate the effect.
